Elegoo resin vs. Prusa resin vs. PETG vs. PLA
Ғылым және технология
With resin 3D printers becoming more accessible than ever, one of the big unknowns is still how strong and usable the UV resin prints actually end up. But that’s exactly what we’re going to find out today by testing Elegoo ABS-like resin vs. Prusa Tough resin vs. DAS FILAMENT PLA vs DAS FILAMENT PETG!

My big issue with resin prints is that they seem to continue to cure and become more brittle over time. PLA and PETg do get more brittle as well. I'd love to see a "6 month followup" where you print some parts in common materials, let them sit out in ambient for 6mo-1yr and then retest them to see how the properties changed over time

I can follow up on this. It all depends on the resin. Engineering resins that I have tested like Siraya Blu and Tenacious don't change over time. In fact it's recommended to cure them under high UV power at 60c for 1 hour or more. Now the cheaper resins on the other hand do become more brittle. And as an extra bonus Glock frames made from a Siraya blu and tenacious mix perform rather well.

Resin prints most definitely are affected by print orientation. Just touch it with a soldering iron and you'll see the way it delaminates at print layer. Cure your resin prints in water. It will get rid of the sticky surface. The reason for stickiness is the oxygen in air which blocks the curing process. Water bath solves that. The fact that one resin is transparent and the other is opaque in visible light says nothing about their transparency in UV. Not testing resin prints printed with different layer exposure times is also something that should be addressed.

Hi, new to resin printing as a concept. Just watching some vids and came across this one. Whats the reasoning behind oxygen causing curing issues? Reason I ask is because of the obvious. While the air we breath is O2, water is H2O. Both containing oxygen. Could water be better not because of oxygen differences but maybe rather the extinction coefficient of water? IV doesn't travel straight through water, it actually reflects/mirages through water. Perhaps this causes the models to receive more UV overall, as the angles would be more "random"? I know UV loses strength the deeper the water, but I don't think a depth of 8" of water would have any meaningful effect on the degradation of the UV rays.

clear resins are stronger that standard solid blue /solid white and especially solid grey. also washable resins are uniformly weaker. shear fracture is a real problem (twisting). eSun has a hard/tough resin that I've had good success with, although it uses a more complex post curing regimen.
Tom, I would love to see this test with the siraya blue and the siraya tenacious blended with other resins.

I’ve been noticing that the curing times of resin are SIGNIFICANTLY greater that what anyone with a KZread channel has been stating. Using the Elegoo ABS Like resins, and a 60W UV lamp, I’ve been noticing that it takes at least 2 hours to cure prints, if not longer. There is a huge difference in stiffness with those that have been cured for 2+ hours, and those under 2 hours. Which brings up another point. It would take days to weeks to cure prints outside under a bright Sun, even here in San Diego where we typically have a UV index between 8 and 12. It would be interesting to see you and CNC Kitchen do some research into this from both the resin manufacturer side, and actual tests.

Deneteus I should have said that it isn’t practical today, to use UV bulbs for anything outside of extreme environmental conditions (i.e. extreme heat). Bulbs can’t produce as narrow a bandwidth of light as LEDs can, they are extremely expensive to manufacture, they have short lifetimes, and they lose at least 10-20% of their energy just from shining through their encloser (crystal or other, as real glass blocks at least 90% of the UV). Anywho, since I am using a UV lamp of the wavelength that the resin is specifically designed to react to, this is not an issue.
@SianaGearz

I suspect short cure just makes the print possible to handle and kicks off the curing, but does not achieve high degree of crosslinking, because that's just what manufacturers optimise for, they want to occupy the curing machine as little as possible and ship things to the customers and hope they'll take a while to actually load and break things, weeks or so. I suspect the curing once started doesn't actually stop when you stop blasting it with UV, it just continues more slowly. Which then brings the issue that if my conjecture above is true, then all kinds of mechanical tests on prints that were done yesterday, are not valid during the life of the part several months after initial manufacture.
Beautiful studio Thomas!!!

Resins have become far more interesting recently - it's good to see manufacturers bringing new variations to market. Also, beginning to see the appeal of Prusa's curing station, although still quite costly compared to a couple of nail curing stations and some 405nm lamps.
Any way you could do some cold weather testing with some test prints? I'm interested to see how resin prints hold up in freezing temps vs filaments such as PETG, PLA, ASA.
Thank you for taking the time to make this video sir. I am sorry to hear about what ever happened with Amazon. I don't know much with 3D printers, I am so new to it, my order for mine has not shipped yet.

really nice tests. can you share the holder and the structure of your test and test files? I would like to build it after
It would be great if you could get some higher grade resins (dental-tough-flexible etc) for testing.
That was truly comprehensive! Thanks 👍 🙏
nice video. did you by chance had a look at the deformation of the springs after applying load? Maybe you could run a test to see how much each material could take before loosing shape :)
Very nice test!
I don't normally laugh out loud at KZread, but "Stop... Hammer Time" got me. Great video Tom - weird to see people think that CNC Kitchen did this first!
How did you get that B+ filament from das filament? Every time I look it is out of stock
Would love to see an analysis of the effects of water curing in the CW1.
Happy Resintine's Day, Tom! I wonder how the resin hammer-test parts would do if you made multiple thin parts that you put in the holder side by side. Being thin, they might cure better.
A very informative video. Thank you. Kind of disappointed that none of the upgraded PLA's were tested nor any of the nylon's. I've been using PLA+ and PLA2 for over a year and haven't used regular PLA for quite a while. I'm about to try Filacube's HT-PLA+ which has a glass transition temperature of 85C after annealing (PETG is 80C).
Love the channel good sir. Unrelated question, what kind of workbench are you putting together in the beginning?
Great video! Very informative and very well done. Thank you!!
Your video gave me an idea. What if you added finely ground or chopped glass or carbon fiber in the resin. To keep it in suspension attach a tube to both end of the tray and use a small centrifical pump to circulate the resin across the tray while printing. I could probably waste my time and file a patent on this but I already have too many now. In addition the circulating system could have an external reservoir so that you don't have to continually fill the tray on large prints. Great channel and good luck.
Nice tests! Would be interesting to also test Formlabs resin, especially their glass filled and Tough resin. It's also 4x the price so you would expect better performance.
Lovely, didn't miss Stephan one bit!
My experience with resin for parts that undergoe repeated stress is that layer orientation does matter. I encourage you to print those test pieces flat and at 45/45 angles across the xy axis.

Would love to see the effect of doubling the layer exposure time
Filaween was a great tool for learning. However, as long as we buy quality filaments, there do not seem to be huge differences. It is important to understand when to use which material, but I usually do not choose one specific manufacturer to get the last 5% of material strenghts into the design. For the resins, we now see massive differences in properties. Differences of the scale between different materials in FDM. In this case, choosing the right manufacturer definently needs to be considered for mechanical parts. This was one of the most informative videos in the 3D printing space I have seen in a long time. Keep it up! I would love to see an analysis of the difference between transparent and opaque materials. And of course between manufactureres in general. I'd recommend a focus on "tough resins". Since this is what would be chosen by the customers for mechanical prints. "Normal" resins, for figurines etc. will be used less for mechanical prints. So there is less gain in analyzing them.
Just checking, is there a moisture component to some of the resins used in 3D printing that will evaporate out over time? Or are you just referring to how completely set the resin is or isn't when you describe it as dry or wet?
Thank You, this is very informative and helpful. Keep this up. keep creating informative videos like this. 🙂🙂🙂
I can confirm that clear resin has greater difficulty curing than a solid color resin. I encountered this when going from basic grey to a clear green resin. The clear needed double the burn in layer time to even stick to the build plate.

Please add heat deflection to your testing. Super interested in knowing if resin can be used making a cooling fan for example. Not allot of info out there on resin heat deflection properties in comparison to FDM materials. As always, thank you for the awesome videos.
Hi there. I’ve just been watching your video very good too might I add. Have you ever tried creating a part. And placing say a rod like part inside the model. So while your printing it. You stop half way through your print and insert your rod or carbon fibre part. Then restart your print.? Just curious if anyone else has or not.?🤔
I am curious how all of this stacks up against normal 2-part mix resins like Alumilite corp AlumiRes RC-3. I am only using my printer to make positives that I can mold in RTV and then mass produce with a faster (and presumably stronger) resin part because it has no weak adhesion lines.
cool video. makes me curious on glass transition temps,
Valuable information! Thank you.
More of those tests 👍 Currently I'm doing some of these tests myself, creating a model of a WW1 biplane (Roland D VI a). I want to keep it's fragile look while beeng robust enough to survive the unavailable conflicts with mother earth and it's gravity 😒 without getting too heavy. On the weight side, balsa wood wins all the way but when it comes to shape accuracy and robustness, PLA+ is doing very well. I am still testing the combination of 3D printed parts with CFK rods or carbon rowings+epoxy at some spots. Anyway, very informative and keep doing this 😉
Awesome test, thank you Thomas! You should check out Sirayas tough resins such as Siraya Blu and Blu clear. They outperform Elegoos resins by a large margin in my experience.

Hi, thanks a lot for your apport, do you know If resins still have the issues about that has to be washed in isopropyl alcohol, the odor and that are unfriendly for skin? I refer to its usage after is cured, eg. A wrist watch done with resin would have odor and could damage my skin?

Wow awesome video Thomas. Thanks for this. I'm really surprised the resin is that good. I only have experience with PLA and PETG and noticed that PLA, being semi crystalline, seems to become more brittle over time, or is even seemingly getting a higher Young's modulus or lower density based on the sound. I would also expect a UV curable resin to have aging issues. I did not notice that of PETG (yet). Perhaps a suggestion to store some of these samples in a representative space and repeat the tests a year from now? I would prefer more mainstream blends though.
Love the testing videos👍
id like to suggest additives to the resin. such as siraya tenacious and Monocure Flex100 for even more str
That's interesting, I know petg is durable but I didn't think fully dried that is would flex so much. Awesome video 👍
Been missing tests with resin.. Would be nice to see some of the eco resins aswell :)
hi, great vid and considerations. what about tests with temperature-stress, chemical agents stress (e.g. gasoline, petrol, alcohol, ...), water resistance.. thanks
Can we get an updated version including SirayaTech along with their Tenacious additives? That would be super interesting to compare how much Tenacious helps.
Prusa also has an ABS like resin. I would have liked you to test it, because it is pretty expensive.
Excellent video. Super interesting to see how resin compares to fdm. And congratulations on the new lab, but I would be weary of the AI you installed.
Thank you for the informative video. Although the SLA did well for some reason I expected it to be even stronger.
What about consumable materials price for a chosen test object, printing time, human prep time, and ease of printing /repeatability? Are PLA vs resin markedly different? Great video, cheers!
What would be very interesting it how hard the surface is, i.e. what will happen if you make gears out of these plastics? Will the teeth sand away?
What about different infill algorithms? like gyroid etc. They will distribute the tension and give it micro flex points that should make it stronger right?
amazing video tom
Just wondering if you've ever used the tmc 2209 drivers? Are there any better drivers for 3d printing, and how to they compare to the 2130
This was one i was waiting for .Are you sure there is no layers in sla printing? You should test this also horizontal print and vertical print.
I wonder if you could change your resin printer test shapes to include a middle hollow core so UV light could be introduced into the center of some samples? Maybe make it 5mm diameter so you could stuff a 5mm UV led in each end? This way you could test with and without internal curing.
The rubbery feel of the Elegoo is by design, one of the ABS-like factors, as ABS also has that kind of rubbery texture.
While I agree most folks don't tune all their filaments, this leaves one problem nevertheless: You might test one material that's just about perfectly tuned-simply by chance-and another that's way off from its perfect settings. If all are equally "mistuned" it's fine, but without calibration, you just never know where they stand. Apart from that: very interesting test, thanks!
it would have been interresting to test several orientations for the resin as well , just to be sure if it s a factor or not. Thanks for the video anyway from which i got valuable informations.

Then there is time for me to learn software 😁
Finally some actual data about the durability of resin prints!!! 😁Very interesting results. The dimensional accuracy of SLA with at least PETG material performance make a very compelling argument for using SLA to produce functional parts. If you're going to do more testing in future, may I suggest: Does prolonged UV exposure affect ductility? The claim / doubt / worry is that the resin will continue to cure over time, and become more brittle. Temperature resistance data for resin prints is often hard or impossible to come by, so that would be very useful data. Thanks for the great video!

It doesn’t take a super long time either and these are stored indoors (I’ve got FDM gears that are still fine even 6 years later on my printer and it’s sitting right next to a window, so ABS really doesn’t deteriorate as bad as resin even after a few years)
